chore(nuget): custom nuget release task

[stijnmoreels]

Since the new Ubuntu build image on DevOps does not have mono installed, it means that some tools like NuGet are not built-in installed anymore. As a migration, they recommend doing it yourself.

This PR uses the dotnet nuget push instead (like we did with the MyGet release), which fixes this problem.
